From Pain to Power: A Strength Training Transformation Story with Mac & Gil

Every lifter’s journey is unique, but few demonstrate resilience quite like Gillespie’s—a man who began with chronic pain, shaky confidence, and a belief that strength simply wasn’t for him. In this strength training transformation story from the Beast Over Burden podcast, hosts Niki Sims and Andrew Jackson sit down with Coach Mac McGregor and his long-time client to unpack the years of setbacks, breakthroughs, and psychological hurdles that shaped Gillespie’s path from a hesitant beginner to a capable Coast Guard volunteer. Through stubborn consistency, patient coaching, and a relentless commitment to the process, Gillespie shows what’s truly possible for anyone who starts later in life, battles pain, or doubts their own potential.

How It Started — From “Unathletic” to Uncertain Beginner

Gillespie’s story begins in a place many lifters recognize: not seeing himself as athletic. As a child, he was always last in school races. As an adult, he gravitated toward swimming—the one activity where he felt even moderately capable—but never discovered strength training. When he finally stepped into a gym as an adult, he turned to the internet for guidance and, like countless beginners, ended up lost in high-volume “six-pack” routines that left him exhausted but unchanged.

Everything shifted when he met two local masters lifters who introduced him to the barbell. Their early encouragement planted the seed, but he still lacked structure, confidence, and technical understanding. When he eventually connected with his first online coach, Carl Schutt, he discovered real programming but still carried years of movement issues, nagging injuries, and doubt.

By the time lockdowns hit, Gillespie’s training unraveled. His gym closed, his weight yo-yoed, and years of physical and psychological baggage resurfaced. What he didn’t realize was that this difficult season would eventually lead him to the partnership that changed everything—working with Mac McGregor.

Through it all, Gillespie remained quietly determined. Even in the early stages, he kept showing up, even when training felt clumsy, painful, or embarrassing. That willingness to try—despite fear—would become the foundation of everything that followed.

Rebuilding From the Ground Up — Coaching, Pain, and True Progress

When Gillespie first started working with Mac, he wasn’t just a lifter with inconsistent technique—he was someone convinced he might be broken. Nearly every lift hurt. His confidence was fragile. And he arrived ready to declare defeat, convinced he simply wasn’t built for strength.

Mac had a different perspective. He recognized that the key was not intensity but patience. Instead of chasing linear progression or clinging to numbers, they stripped everything back: empty bar squats, 40-kg deadlifts, slow tempo work, troubleshooting movement patterns, and experiments to find tolerable variations. Some weeks he could squat but not deadlift. Other weeks bench worked but pressing didn’t. Together, they treated training like detective work rather than punishment.

The real breakthrough wasn’t physical—it was psychological. Mac helped Gillespie decouple progress from expectations. Success wasn’t measured in PRs but in good reps, symptom-free sessions, and small wins. This shift allowed Gillespie to stay engaged through long stretches of inconsistency and pain.

Slowly, technique improved. Confidence grew. The setbacks became less frequent. The movement patterns began to click. And eventually, something remarkable happened: instead of fighting his body, Gillespie began to understand it.

That patience—shared by coach and client—became the engine of his transformation.

The Turning Point — When Strength Finally Took Off

After years of slow progress and constant troubleshooting, everything changed around 2023. Gillespie improved his nutrition, increased protein intake, and stopped fighting to stay lean. Instead, he focused on fueling his training. Suddenly, the aches and pains that once governed every session began to fade.

With a stable foundation and better recovery, the numbers finally started climbing—fast. His squat hit 140 kg, deadlift soared to 187.5 kg (over 400 lb), his bench passed 110 kg, and his press reached 75 kg. For someone who once struggled to bench an empty bar, these were not just PRs—they were breakthroughs in identity.

Even more meaningful than the numbers was the confidence that came with them. Gillespie no longer saw himself as the unathletic kid or the fragile adult. He saw himself as capable, durable, and competent. That confidence spilled into every other part of his life, shaping personal relationships, mental health, and even career choices.

This stage of his strength training transformation story shows how progress often looks: slow, slow, slow…and then suddenly unstoppable.

Setbacks, Lyme Disease, and the Power of Starting Again

Just when things were at their peak, everything collapsed almost overnight. Gillespie developed unexplained pain, fatigue, and a resurgence of old injuries. After months of uncertainty, a test finally revealed the cause: Lyme disease.

The months that followed were brutal. His lifts plummeted. His energy vanished. Basic movement felt impossible. And yet the mindset he’d built—the process-focused approach, the ability to adjust, the willingness to train even when the load was light—carried him through.

After treatment, he returned to a simple novice linear progression, starting with embarrassingly light weights. But this time, he wasn’t discouraged. He understood the process. He trusted it. And once again, the numbers began climbing.

His recovery demonstrates one of the episode’s most powerful themes:
If you know how to train, you always know how to come back.

This is what makes strength training not just physical work but a lifelong skill.

Becoming a Different Person — Strength, Service, and Identity

Perhaps the greatest proof of Gillespie’s transformation is not in the weight on the bar but in the uniform he now wears. After building physical strength and mental resilience through training, he joined the Coast Guard in the Isle of Skye—something he once believed impossible.

The work is demanding: carrying equipment across rugged terrain, assisting in rescues, and even participating in body recoveries. Strength isn’t theoretical in these moments—it’s necessary. And now, he possesses it.

Gillespie also found a deeper confidence socially, emotionally, and personally. Training didn’t just change his body; it changed how he sees himself and how he participates in the world. He describes it as an evolution he wishes he’d started decades earlier.

This strength training transformation story is ultimately about reclaiming agency—reducing chronic pain, building competence, forming a friendship with a coach, serving his community, and rewriting the way he thinks about his own abilities.

It’s proof that strength is not reserved for the gifted, the young, or the naturally athletic. It’s for anyone willing to start, struggle, and keep showing up.
